what is the difference between unlistedscript and content script?

[xunziheng]

Could you tell me the difference between unlistedscript and content script? If I want to manually inject content script based on URL, how can I do it? (Matches can't satisfy me.)

Regards, wxt

for example:

export default defineBackground({
  main() {
    console.log('Hello background!', { id: browser.runtime.id });

    browser.tabs.onUpdated.addListener(async (tabId, changeInfo, tab) => {
      if (status === 'complete' && isTestPage(url)) {
        await (browser.action ?? browser.browserAction).enable(tabId);
        // >>>>>>>TODO: how to inject content script? (main world needed)
      } else {
        await (browser.action ?? browser.browserAction).disable(tabId);
      }
    });
  },
});

Unlisted scripts aren't added to the manifest. Content scripts are listed in the manifest and are automatically registered to run in tabs.

You can use the scripting API to run code in a tab whenever you want: https://developer.chrome.com/docs/extensions/reference/api/scripting#concepts_and_usage

I saw that browser.scripting.executeScript() only support inject isolated world script right.
but the chrome extension guide show 2 worlds:

That's not true. You can execute the script in the main world.
